Abstract

X-rays or .gamma.-rays are detected by irradiating a beam of high energy radiation onto a crystalline bismuth oxide compound having the formula Bi.sub.10-14 X.sub.1 O.sub.n wherein X is at least one element selected from the group consisting of Al, Ga, Ge, Si and Ti and n is a numeral substantially equal to the stoichiometric amount of oxygen within the compound. The above bismuth oxide crystalline compound may be placed in a radiation dosimeter or be applied as a radiation-sensitive coating on a cylinder or plate of an apparatus for producing electrostatic copies (i.e., an in a xerographic process or the like).
